Chapter
is an emerging hot field for improving light-harvesting and promoting photon efficiency. The integration of noble metal nanostructures (Ag, Au) with active metals (Pd, Pt, Ru) in arrangement has been establ...
Article
This mini-review contrasts the characteristics of traditional heterogeneous (solid) catalysts with those of homogeneous ones: the nature of the active sites in each case is very different, a fact well illustra...
Chapter
Enzymes catalyze the most fundamental reactions in organic chemistry from simple oxidations of straight chain alkanes to complex C–C bond forming reactions with exceptional selectivity. Mimicking the active si...
Chapter
The advantages that flow from the availability of single-site heterogeneous catalysts are many. They facilitate the determination of the kinetics and mechanism of catalytic turnover and render accessible the e...
Article
Zeolite encapsulated amino acid complexes such as Fe-proline, Fe-histidine and Cu-valine have shown significant promise in the selective oxidation of hydrocarbons such as cyclohexane and benzylic alcohols. Thi...
Article
Designed nanoporous solids are highly effective in facilitating shape-selective and regiospecific catalytic conversions in the synthesis of fine chemicals, pharmaceutical intermediates as well as in sustainabl...

Article
Using open-structure (nanoporous) solids, advantage may be taken of single-site catalytically active centres to effect an enormous range of conversions of organic compounds where regio-selectivity and shape-se...
Article
Two types of single-site heterogeneous catalysts have been designed so as to facilitate either the side-chain oxidation or ring-hydroxylation of toluene in O2 (solvent-free) or by employing aqueous (H2O2) or orga...
Article
Pyridinium dichromate, chromium trioxide and CrAlPO-5 showed a very similar selectivity pattern in the decomposition of cyclohexyl hydroperoxide. CrAPO-5 turned out to be a real heterogeneous catalyst, most li...
Article
We analyze the merits of an approach to the design of enantioselective catalysts that relies on constraining an anchored organometallic complex at the inner walls of mesoporous silica. Two distinct metal cente...
Chapter
Microporous, transition metal ion-substituted aluminophosphate molecular sieves have attracted considerable attention over the last decade owing to their shape-selective catalytic properties for both acid-cata...
Article
A survey is given of the catalytic methods potentially available for the production of adipic acid by the oxidation of readily available hydrocarbon precursors under environmentally benign conditions. Encourag...
Article
Terminally oxidized hydrocarbons are of considerable interest as potential feedstocks for the chemical and pharmaceutical industry, but the selective oxidation of only the terminal methyl groups in alkanes rem...
Article
The selective oxidation of cyclohexane to cyclohexanol, cyclohexanone and adipic acid using molecular oxygen as the oxidant and at moderate temperatures (403 K) has been investigated over four different cobalt...
